issue in TPC TimeGain calibration and laser calibration since software update including the TPC GPU tracking improvements

• laser calibration fails, some suspicious negative vdrift correction values quoted in the logs
  • will run a laser run with old software epn-20250905  (to get logs for comparison) and rawtf storage (for local reconstructions)
• running local reconstruction and TimeGain calibration
  • on GPU, CPU
  • old software epn-20250901 and new software epn-20250925.2 
  • TPC track dEdx and lokal TimeGain calibration look fine for oldSW+GPU/CPU and newSW+CPU, but large difference with newSW+GPU
  • TPC track dEdx in OROC3 for 100 TFs of run 566656 which uses an already bad TimeGain object initially
    • upper row: new SW, lower row: oldSW
    • left: GPU, right: CPU
